Specification of Letters Patent.

Application filed March 27, 1913. Serial No.l757 ,-38. J

To all whom it-ma e concern:

' Be it known that I, WILLIAM D. BRoNsoN, citizen of the United States, residing at Duke, in the county of Jackson and State 7 of Oklahoma, have invented 'certain new and useful Improvements in Exhaust-Heaters for Steam or Gasolene Engines, ofwhich the following is a specification.

My invention relates'to devices for heating Water, and particularly to means whereby the exhaust from a steam orinternal combustion engine "may be used for heating water. I The primary object of my invention is to provide a simplefeflective,"and economical mechanism adapted to provide a base or bed for an engine and so constructed as to provide means whereby the exhaust from the engine may be used forthe purpose of heating water. i

A further object of the invention is to provide means whereby the exhaust from a steam or internal combustion engine may be carried into a heating chamber and there distributed around water pipes passing through the chamber into which theexhaustis introduced.

For a full understanding ofthe invention,

reference is to be had' 'to' the following description and accompanying drawings,'-j in .whicl1:'. Figure 1 is a perspective. view or my heater applied to an internal]combustion engine; Fig.2 is a longitudinal horizontal section of my heater; Fig. 3 is a vertical section thereof, the interior thereof being shown in elevation; and Fig. & isa vertical transverse section on the line of Fig. 3. Corresponding and'like parts are referred to in the'following description and'indicated in all the views of the accompanying drawings by the same'reference characters.

As illustrated in the foregoing figures, 2 designates an exterior casing which is closed at one end by an integral web 3 and at-theother end is formed. with a laterally projecting flange 4-, perforated for the passage of rivets to secure a head 14 to the casing. This casing 2 is formed with a base 5 where by the casing may be supported upon aconcrete or brick foundation 6. Mountedlupon the casing 2'is a saddle 7 u on which any suitable engine 'is-adapted to be supported,

bolted. v s

The casing 2 is provided with a water inlet pipe 8 adapted to l6tld1l0111 any suitable source of supply, this pipe being pro vided with avalve 9. Leading out from the casingis awater outlet pipe 10, alsoprovideol with a valve 11. Preferably the water and to which the bed plateof the engmeis Patented Dec. 15, 1914.

inlet pipe and the outlet pipe-are disposed at opposite ends of the casing2 and at oppo- The casing 2 may be,

s'ite sides thereof. and preferably is, provided with a water gage12.""

' Disposed within the casing '2 and insertible therein 'throughthe end 3 ofthe casing,-

is a cylinder 13 of less diameter than the T casing 2. This cylinder'l3 is closed atone end by means' of a head 14; this offsuch size as tocl'ose thefchamber' formed by thecasing2 and to; be bolted to the flange I 4. Inasmuch as the casing 13 is smaller than the casing*2, a' water space will beleft entirelyaround the casing13, and as the casing 13 is shorter than the casing 2, awater spacejwillibe left at the end of the casing.

The endof the casing 13 opposite the head 14: is closed by means'of a head loprovided with a plurality-of openings 16' from which head being" extend water pipes 17. These pipes extend j inward into the interior then-extend outwardand open upon the cir cumferenceiof the casingl j Preferably the perforations 16 are arranged in; a circular series, anddisposed at the center of the circle defined by these perforations is a hollow conical-spreader or defiector 18. Entering the head 14L at a point exactlyopposite the'apex ofthe de: fiector 18 is an exhaust pipe 19 having a nozzle; This pipe 19 extends out through the head'l and is connected by means of an elbow 20 toan exhaust pipe 21 which constitutes the exhaust pipe of the engine. An exhaust outlet pipe 22 extends out of the head 14 and is'connected by" means of an elbow 23 to any suitable pipe for carrying away the exhaust after it has passed through the. chamber formed bythe casing 13.

Preferably the ,water inlet pipeS iscontrolled by means of a float valve 23 actuated y it float 24:) This floatv'alve may be of of the casing 13 and The exhaust from an'internal combustion engine or other suitable motor is carried down the pipe 21 and enters the interior of v the casing 13 by means of the nozzle 19,

The space between the casing 13 and the exterior casing 2 is filled with water, and it will be obvious that water will also fill the Water tubes 17 and the interior of the conical .defiector 18. The exhaust is projected by means .of the nozzle 19 against the conical deflector 18, and by .the deflector is spread uniformly throughout the casing 13 and around the pipes 17. These heated products of combustion after they have passed into the casing 13 areicarried ,away y een o e p pe 22, so tha e con n ous current of the exhaust is kept up through the casing 13. It will be obvious also that a continuous circulation of water will be secured through the ,pipes, 17 .and the jacket surrounding the casing 13, .so that every ,portionofthe .water will be subjected to the action of the hot products-of combustion. The water will be heated not only by its passage-through the pipes 17 and by contact .withithe deflector 18, but also by contact with the head 15 and the wall of the casing 13, the water being carried off through the pipe 10 .and used for any suitable purpose. I do not wish to limit myself to the ,precise details of construction illustrated, as it will be obvious .that many changes ;may be made therein. Nor .do I "wish .ito dimit myself to any particular form of engine, as it is readily seen .tha t any engine from-which there is a,hot exhaust be used with my device for the purposeiof heating water. f-It is also P i tha if my tac ment app to internal combustion engines using liquid fuel, the fuel may ;be properly heated by passing into the vcasing 2 and around vthe inner cylinder or casing 13.
